重装了个 macos11， brew 好些软件不支持， xcode 指定到 13， flutter 又要求 14，又得升级回去才行😂

We (and Apple) do not provide support for this old version. It is expected behaviour that some formulae will fail to build in this old version. It is expected behaviour that Homebrew will be buggy and slow. Do not create any issues about this on Homebrew's GitHub repositories. Do not create any issues even if you think this message is unrelated. Any opened issues will be immediately closed without response. Do not ask for help from Homebrew or its maintainers on social media. You may ask for help in Homebrew's discussions but are unlikely to receive a response. Try to figure out the problem yourself and submit a fix as a pull request. We will review it but may or may not accept it.

Do not report this issue: you are running in an unsupported configuration.

最麻烦的是要编译一个 1.10 的 svn ，公司的 svn 又要 https,证书又有问题😭，只能旧版本连的上

不能虚拟机？

[treblex]

@MrKrabs 配置不高，装虚拟机很慢，而且 windows 的也要找旧版本的 svn

brew 这个好弄，用 git 把 brew 退回到最后一个支持你所在系统的 commit ，再禁用更新😂😂

@jianzhao123 学到了，下次再装个 12 试试，现在升回 14 还挺安静的，之前手贱升级的 15beta ，装在包里一直不休眠烫手
